It's one of the very oldest plastic ship kits. It originally appeared in 1954, under the name The Sullivans. (Note for folks interested in details: the word "The" in this case is part of the name. The ship - like her modern successor - was named for the five Sullivan brothers, who were killed in the Pacific during WWII.) According to the bible on the subject, Thomas Graham's Remembering Revell Model Kits, the scale is 1/301. (I imagine Mr. Graham got that figure by dividing the prototype length by the length of the kit's hull. Maybe the designer was aiming for 1/300 scale and goofed. Or maybe he was just trying to make the kit fit a standard box.)
It's been reissued several times. I seem to recall that in at least one of those reincarnations the no. 2 5" gun mount got replaced by a hedgehog launcher. Otherwise, I believe, all the reissues are identical except for the decal sheets.
By today's standards this kit is about as crude as they get. But its impact on the hobby was enormous. It was one of a small fleet of Revell products that created the market for plastic warship kits.
Shortly thereafter Aurora got into the game with its own ship series, including a Fletcher-class destroyer originally issued under the name U.S.S. Bennion. I haven't seen that one in years and I don't know what scale it was on, but it was considerably smaller than the Revell entry. I remember thinking it was a pretty nice little kit, but I suspect the level of detail was about like that of the Revell one.
Either of these kits makes a nice exercise in nostalgia. Anybody looking for an accurate replica of a Fletcher-class destroyer, though, needs to stick with the Tamiya offerings - either 1/350 or 1/700.
Youth, talent, hard work, and enthusiasm are no match for old age and treachery.
